如何處理「沒有查找ID ...」在Android活動與片段

我希望我的應用程序向large-land模式中的用戶顯示此屏幕，以便他可以輸入，按下按鈕，並查看輸出全部在同一個屏幕上。如何處理「沒有查找ID ...」在Android活動與片段

enter image description here

對於任何其它模式時，欲被顯示一次一個以上所示的兩個窗格，以該順序，其中，所述第二屏幕出現當用戶按下該按鈕時，在此之後按下back按鈕返回到「輸入」屏幕左側：

enter image description here enter image description here

我做了什麼工作，在顯示第二屏幕上正確的輸出點，但隨後我得到「未找到ID視圖「container然後發生異常

這裏上述用於第一屏幕是xml：

device(large-land).xml

<LinearLayout                      xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width= "match_parent" android:layout_height= "match_parent" 
    android:id     ="@+id/linear_layout_container_in_large_land_device_xml" 
    android:weightSum   ="3" 
    > 
    <fragment 
     android:name="com.dslomer64.fragments.InputFragment"    android:layout_weight ="2" android:layout_width="wrap_content" android:layout_height="match_parent" 
     android:id    ="@+id/inputFragment" 
     tools:layout   ="@layout/input_fragment" 
    /> 
    <fragment 
     android:name="com.dslomer64.fragments.OutputFragment"    android:layout_weight ="1" android:layout_width="wrap_content" android:layout_height="match_parent" 
     android:id    ="@+id/outputFragment" 
     tools:layout   ="@layout/output_fragment" 
    /> 
</LinearLayout>

device.xml（用於非large-land）

<FrameLayout                      xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" 
    android:id="@+id/container" 
/>

input_fragment.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> 
    <TextView 
     android:id ="@+id/tvInMainFragment"              android:layout_width ="wrap_content" android:layout_height="wrap_content" 
     android:text="How many?" 
     /> 
    <EditText                      android:layout_width="wrap_content" android:layout_height="wrap_content" 
     android:id="@+id/etxIn_input_fragment" 
     android:text="3" 
     /> 
    <Button 
     android:id="@+id/btnIn_input_fragment"               android:layout_width="wrap_content" android:layout_height="wrap_content" 
     android:text="Press to get output in OtherFragment" 
     /> 
</LinearLayout>

output_fragment.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"       android:layout_width="match_parent" android:layout_height="match_parent" > 
    <TextView 
     android:id="@+id/txvIn_output_fragment"                 android:layout_width="wrap_content" android:layout_height="wrap_content" 
     android:text="Output will go here in OutputFragment" 
     /> 
</LinearLayout>

MainActivity.java

public class MainActivity extends Activity 
{ 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.device); 
     if (findViewById(R.id.container) != null) { 
      InputFragment inputFragment; 
      inputFragment = new InputFragment(); 
      getFragmentManager().beginTransaction() 
        .add(R.id.container, inputFragment) 
        .commit(); 
      }  
    } 
}

InputFragment.java

public class InputFragment extends Fragment 
{ 
    public View onCreateView(LayoutInflater  inflater, 
          ViewGroup   viewGroup, 
          Bundle    savedInstanceState) 
    { 
     View view = inflater.inflate(R.layout.input_fragment, viewGroup, false); 
     Button btn; 
     btn = (Button)view.findViewById(R.id.btnIn_input_fragment); 
     btn.setOnClickListener(new View.OnClickListener() { 
      public void onClick(View v) { 
       OutputFragment outputFragment; 
       outputFragment = new OutputFragment(); 
       if (getFragmentManager().findFragmentById(R.id.inputFragment) == null) { 
        getActivity().setContentView(R.layout.device); 
        FragmentTransaction fragmentTransaction = getFragmentManager().beginTransaction(); 
        fragmentTransaction.replace(R.id.container, outputFragment); 
        fragmentTransaction.addToBackStack(null); 
        fragmentTransaction.commit(); 
       } 
       getActivity().setContentView(R.layout.input_fragment); 
       EditText etx = (EditText) getActivity().findViewById(R.id.etxIn_input_fragment); 
       fillFragmentOtherWithInfo(etx.getText().toString()); 
      } 
     }); 
     return view; 
    } 
    public void fillFragmentOtherWithInfo(String ks) 
    { 
     getActivity().setContentView(R.layout.output_fragment); 
     TextView tvOther = (TextView)getActivity().findViewById(R.id.txvIn_output_fragment); 
     String s = ""; 
     for(int i = 0; i < parseInt(ks); i++) 
      s += ("\n" + (char)(i+65)); 
     tvOther.setText(s); 
    } 
}

會發生什麼事都好，在顯示第二屏幕上的輸出點。它顯示正確，但隨後我馬上拿到前面帶有此消息的異常，我不知道該做些什麼什麼：

03-02 15:59:52.987 7901-7901/com.dslomer64.fragments E/FragmentManager: No view found for id 0x7f070000 (com.dslomer64.fragments:id/container) for fragment OutputFragment{41ecc848 #1 id=0x7f070000}

container是FrameLayout在device.xml的id（非-large-land），在MainActivityonCreate的片段事務的.add部分中引用。如果我使用.replace而不是.add，我會得到同樣的錯誤。

以下是錯誤的整個文本：

下面的代碼產生所需活性。 WITH Fragment s。
